Check this page for existing styles which you can reuse to create a similar button.

But there is no style that renders a button to look like an app bar button (e.g. a circle instead of a rectangle). You will have to render this on your own using this brush:

PhoneChromeBrush

or this color:

PhoneChromeColor

But you should first check the Microsoft style guidelines whether this is a good idea or not. I am not aware of a limitation to not mimic app bar buttons, but the user would probably not expect to see such buttons somewhere else than on the bottom.
